Can we all agree to bury our fond, pathetic hopes about how home computers are good for poor children?


Randall Stross reviews recent research on "home computer's educational impact on school children in low income households":

... [T]here is an automatic inclination to think of the machine in its most idealized form, as the Great Equalizer. In developing countries, computers are outfitted with grand educational hopes, like those that animate the One Laptop Per Child initiative, which was examined in this space in April. The same is true of computers that go to poor households in the United States.

Economists are trying to measure a home computer’s educational impact on schoolchildren in low-income households. Taking widely varying routes, they are arriving at similar conclusions: little or no educational benefit is found. Worse, computers seem to have further separated children in low-income households, whose test scores often decline after the machine arrives, from their more privileged counterparts.

Here are the summaries of a couple of studies:

Professor [Ofer] Malamud [economist at the University of Chicago] and his collaborator, Cristian Pop-Eleches, an assistant professor of economics at Columbia University, did their field work in Romania in 2009, where the government invited low-income families to apply for vouchers worth 200 euros (then about $300) that could be used for buying a home computer.

The program provided a control group: the families who applied but did not receive a voucher. They showed the same desire to own a machine, and their income was often only slightly above the cut-off point for the government program.

In a draft of an article that the Quarterly Journal of Economics will publish early next year, the professors report finding “strong evidence that children in households who won a voucher received significantly lower school grades in math, English and Romanian.” The principal positive effect on the students was improved computer skills.

At that time, most Romanian households were not yet connected to the Internet. But few children whose families obtained computers said they used the machines for homework. What they were used for — daily — was playing games.

In the United States, Jacob L. Vigdor and Helen F. Ladd, professors of public policy at Duke University, reported similar findings. Their National Bureau of Economic Research working paper, “Scaling the Digital Divide,” published last month, looks at the arrival of broadband service in North Carolina between 2000 and 2005 and its effect on middle school test scores during that period. Students posted significantly lower math test scores after the first broadband service provider showed up in their neighborhood, and significantly lower reading scores as well when the number of broadband providers passed four.

    Is there separate stats for cases with and without parental super-vision.
    Or cases where
    Parents teach geography over Google-Maps and weekly assignments asking kids to research topics over Wiki-Pedia, possibly one per week :)
